SHAKING GRATE.

SPECIFICATION forming part of Letters Patent No. 289,680, dated December4, 1883.

Application filed March 5,}883. (No model.)

To all whom it may concern: Be it known that I, JoHN H. MoKEowN, citizenof the United States, residing at Salem, in' the county of Columbianaand State of Ohio, have invented a new and useful Shaking Grate, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to shaking grates for all kinds of stoves; and itconsists in certain improvements in the construction of the same, whichwill be hereinafter fully described, and particularly pointed out in theclaim.

In the drawings hereto annexed,.Figure 1 is a longitudinal verticalsectional :view of a grate equipped with my improvements. Fig. 2 is avertical transverse sectional View of the same. Fig. 3 is a horizontalsectional view, and Fig. 4 is a detail view of one of the gratebarsdetached.

The same letters refer to the same parts in all the figures.

A in the drawings represents the frame of my improved grate, which isprovided at its ends with inwardly-projecting brackets B B. Saidbrackets are provided with perforations G O, to receive studs or pins DD, projecting downwardly from the cross-bars E E, mounted upon the saidbrackets, upon which they are pivoted by means of the pins 1), as shown.

F and G are the grate-bars. These are constructed, as shown, with websH, connecting the transverse lugs I, the upper sides of which are flat,while their under sides are beveled, as shown, thus insuring greatstrength, while the ashes and clinkers are permitted to pass freely. Thegrate-bars are provided at their ends with downwardly-projecting studsJ, by which they are connected pivotally to the pivoted cross-bars E E,which are provided near their ends with perforations K, to receive thesaid studs J. r

In the drawings hereto annexed only two grate-bars are shown; but Iwould have it understood that any. desired number may be used withoutdeparting from the spirit of my invention. One of the grate-bars, G, isprovided at one end with a shank, L, extending through the side of thestove, and adapted to receive a shaker-iron,- by means of which areciprocating motion may be imparted.

'The operation of my invention will be at once understood from theforegoing description, taken in connection with the drawings heretoannexed. When operated, the gratebars will be reciprocated alternatelyin opposite directions, thus causing the ashes and clinkers to passthrough and down into the ash-pit below. Owing to the peculiarconstruction, any accumulation of ashes at the back wall is prevented,and the draft is therefore at all times free and unimpaired.

I am aware of the patent to Brown, March 25, 1862, No. 34, 731. In thiscase, however, the perforated brackets B are not found, and the partswhich take the place of the levers E in this case are pivoted upon studsextending downward from the ends of the frame, making it necessary toemploy keys or pins for ho1ding them in place, which is obviouslyobjectionable. Again, the grate is arranged to be shaken by a forkedlever applied to one of the end levers, while by my invention one of thegrate bars has a shaking bar extending through the front of the stove.

I disclaim the matter shown in the patent to Brown, above referred to;but

I claim as my invention and desire to secure by Letters Patent of theUnited States' The combination of the frame A, having inwardly-projecting brackets B B, provided with perforations G, the cross-bars E E,having per- JOHN HAMMERSLY MGKEOWN.
